Install/Flashing Instructions:

1. You will need the following things in order to install TWRP on the Slate 21 Pro: 1 USB male to USB male connector, a computer with ADB and fastboot installed, common sense.

2. Turn off device and boot into fastboot mode (Volume Down + Power)

2.5. If your device won't boot into fastboot using that key combo. Enable USB Debugging on your Slate and run the following command from your computer with the Slate connected and on:

adb reboot-bootloader

3. Connect your device to your computer by plugging one end of the USB cord into the lone USB port on the left-hand side of the device and the other end on any USB port on your computer.

4. Run the command “fastboot oem unlock” (no quotes)

5. Select yes on your Slate 21 Pro, after this step you will lose all your data. Vol Up to move Up, Vol Down to move Down, Brightness Up to select.

6. After fastboot has been unlocked, you’ll need to flash TWRP to your recovery. Do do this run the following command:

fastboot flash recovery /path/to/downloaded/TWRP.img

Replace /path/to/downloaded/TWRP.img with where you downloaded TWRP provided by me (Quaesar). You can drag and drop the IMG into Terminal/CMD to do this easily.

8. Profit! You now have the latest TWRP on your device!
